This chemical is primarily used as an intermediate in the synthesis of more complex organic compounds, particularly in the pharmaceutical and agrochemical industries. It plays a key role in the production of sulfonamide derivatives, which are essential in developing antibiotics and other therapeutic agents. Additionally, it is utilized in the creation of dyes, pigments, and other specialty chemicals where sulfonyl chloride groups are required for further functionalization. Its reactivity makes it valuable in coupling reactions and as a building block in organic synthesis.
